Shaykh Kishi and Shaykh Mufeed, had through authentic chains related from Imam Muhammad Baqir (a.s.) that one day Abu Dharr came to the house of Salman. The bowl of Salman was full of soup and fat. During their conversation it so happened that the bowl overturned but nothing fell out of it. Salman straightened it and then continued talking. Abu Dharr was astonished at this. By chance that bowl again overturned but nothing fell out of it.
Abu Dharr’s astonishment increased and he arose from there in deep thought. Suddenly he saw Amirul Momineen (a.s.) there. Imam Ali (a.s.) asked Abu Dharr why he has come away from Salman and what had horrified him? Abu Dharr narrated the strange happening. Imam Ali (a.s.) said: If Salman informs you of the matters he knows, you will indeed say: May Allah bless the killer of Salman.
O Abu Dharr, Salman is the court of Allah on the earth. One who recognizes him is a believer and one who denies him is an infidel. Indeed Salman is from us, Ahlul Bayt (a.s.). Shaykh Mufeed has narrated that Amirul Momineen (a.s.) came to Salman and said: “O Salman, welcome your companion and do not reveal to him the matters that they cannot bear.”
